Abstract

Thioperimidone has been discovered to be useful as an accelerator in the curing of chlorinated ethylenically unsaturated polymers such as polychloroprene with metal oxides such as magnesium oxide or zinc oxide.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A curable chlorinated ethylenically unsaturated polymer composition comprising a 100 parts by weight of a chlorinated ethylenically unsaturated polymer containing mixed therein a curable amount of a metal oxide selected from the class consisting of zinc oxide and magnesium oxide, and an accelerating amount of thioperimidone. 
     
     
       2. The composition of claim 1 wherein the metal oxide is present in 1 to 10 parts per 100 parts of polymer. 
     
     
       3. The composition of claim 1 wherein thioperimidone is present in about 0.2 to 5 parts per 100 parts of polymer. 
     
     
       4. The composition of claim wherein 10 to 80 parts of filler is present. 
     
     
       5. The composition of claim 1 wherein the metal oxide is zinc and magnesium. 
     
     
       6. The composition of claim 3 wherein the metal oxide is zinc and magnesium.
